【Abstract】 For the functional orientation and the objective of water quality protection to Ⅲ-level aquatic ecological functional regionalization along Qinghe River watershed, based on the idea of watershed classifying, regionalizing, grading, and staging, the technology and methods for managing the watershed water quality target are applied to study the application demonstrations of some key techniques, in order to improve the techniques for target management of basin water quality and to provide scientific and technological supports for the water environmental management of Qinghe water basin. These key techniques include pollutant load calculation of a control unit, water environmental capacity computation and allocation, pollutant load reduction, and control of the total pollutants on Qinghe watershed.更多还原
